    "The Electromagnetic Counterparts of Gravitational Wave Sources"

    Abstract: The combined study of gravitational wave and electromagnetic signals from compact object mergers can provide unique insight that is not accessible through each technique alone.  I will review expected EM counterparts of compact object mergers, motivated both by existing observations of short gamma-ray bursts, as well as theoretical considerations.  I will also highlight the observational challenges of finding such counterparts in the large localization regions of gravitational wave sources

    Gravitational waves from binary systems
     
    Abstract: I will review the basic physics of gravitational wave emission from binary systems, describing how the characteristics of a binary get imprinted on its gravitational waves, and thus how measuring these waves teaches us about the binary.  I will describe briefly the techniques which are used to model binary systems, providing an introduction to active research programs in binary gravitational-wave source modeling.

    Dark Matter Searches in Dwarf Galaxies

    Dwarf galaxies have long been considered a prime target in the search for a dark matter signal from the sky. I will discuss the current status of dark matter searches from dwarf galaxies and present results on the analysis of gamma-ray emission and dark matter content in recently discovered dwarf galaxies, including tests that are needed in order to test the hypothesis that any observed emission is due to a conventional astrophysical origin.

    Search for Intergalactic Magnetic Fields and Implications

     
    Abstract: The ongoing search for intergalactic magnetic fields using blazar observations suggests field strength in the 10^(-14) to 10^{-17} G range on tens of Mpc length scales. Such fields can have important implications for the early universe and also raises some puzzles.

    Challenges of Isotopic Molecular Observations

    Abstract: Isotopic ratios provide a powerful method to study the origin of elements and the chemical evolution of the Universe. Spectroscopic analysis is required for any remote astronomical source, with limits on angular resolution, sensitivity, and knowledge of the physical conditions. Molecular lines are particularly well suited as the spectral signatures of different isotopologues are well separated in frequency. I will overview the available spectroscopic observations of isotopic molecular substitutes involving D, 13C and 15N in...
